I've just stumbled across the notion that you shouldn't wear underwired bras in pregnancy for fear of blocking your developing milk duct system.

I've never heard this before (and am still wearing my underwired bras, of course). I Googled it but I can't find any reliable sources online, only message boards on which all the ladies are subscribing to this idea and are advising each other emphatically to steer clear of underwired bras.

Surely if this was true my midwife would have mentioned it to me? Surely if it was true there would be some reliable sources online - like the NHS website - urging me to ditch the wire??

It's an old wives tale, right? Tell me it's a myth - please!!!
